SYK does not Transit Gloria Mundi just yet

Abstract

This note discusses examples of 0+1-dimensional Liouvillean dynamics instigated by the various deformations of the Sachdev-Ye-Kitaev (SYK) model. In reference to such deformations the main focus is on the regions of parameter space where the competing SYK couplings are of comparable strength and can not be treated as each others perturbations in the vicinity of the conformal fixed points corresponding to the pure SYK_q models with different values of $q$. Crossovers between such fixed points ('SYK transits') can be efficiently studied in the equivalent framework of single-particle quantum mechanics.
